THOMAS DE o. RUTH, or NEWARK, NEW JERSEY, AssIGNoR To ROBERT J. EMoRY & COMPANY, or NEWARK, NEW JERSEY, A ooPARTNERsr-ur;

sroonrNG-Maonmn.

To `all 'whom it may concern: A Be it'known that l, Thomas DE C. RUTH, a citizen of therUriited States, residing in Newark, Essex coun ty, Stateful New Jersey, have invented a new and useful 5l Improvement in Spooling-Machines, of which the fol- I lowingisa specitication.- 'Y This invention relates to spooling machinesand par4 Y`tifcularly 'to mechanism for reversing` the movement f ofthe traverse bar of wire-spooling machines. v "In order-to insure the smooth winding of the wire uponthespool it is customary to provide wire-spooling machirieswithguides mounted on a sliding bar which isautomatically reciprocated in a path parallel to the laxdspbout which the spool is rotated during the opera- 'tiono winding the wire on the spool. It isnecessary the range'bl movement of this bar from time `time 4and oniinrily the variation of this range of mi'ivement is accomplished byrdmoving a gageplate the reversing-mechanismffand substituting another gageQplate ofdiferentlength A3F-hepresent invention has for its object 'the provision d' l"ple reversing mechanism for the traverse bar by whiehthe range of movement may be quickly alteredwithout-rnaking any change in the parts oi the .i'reversingQ` l Iijrthe drawings'dorminga part oi this specification, in'which "corresponding parts are indicated by similar of. reference, I have illustrated a preferred emhodiientpf my invention, but itis to be understood that' ariations inthe details of `construction may bev resorte to without exceeding the scope oi the inven-4 tionywhich is clearly defined in the appended claims.

Inthe drawings: Figure 1 is a' perspective ,view of a portion of` a wire-spooling machine of a well known typehaving the improved reversingmechanism for the traversebar applied thereto. Fig. 2 is aplan view of the ldeviceby which the range oi movement of the traverse'bar is determined. Fig, 3 is a view in elevatiorrof the structure shown in Fig. 2, parts being broken `antray or shown in section. i 'Referring to the drawings bythe reference characters, .I I designates a portion of the main frame of the machine, and S indicates a driving shaft to which power is applied in any suitable manner. i L

1-1 are spindles upon which the spools onwhch the wire is to be wound are secured and rotated by belts (not shown) on small pulleys 2 fixed on thespindlcsf lAdjacent to Veach spindle a-guiding device 3 is "provided, each of these guides being mounted on the traver'se bar 4*, which is slidably mounted in brackets 5 onl theframe of` the machine. Movement is imparted to tlrdtlaverse' bar '4 from a screw 6 having oppositely threade'dfportons 7 andA 8. This screw 6 is driven from the shaft S by means or' the friction vwheel 9 and the` disk l0, the former being mounted on the shalt S Specification ofLetters Patent.

and the latter being fast on the end oi the screw 6.

lThe friction wheel 9 is preferably adjusted by means of the serewrll to vary the rate of rotation imparted to the screw 6. ln order to transmit motion to the tieverse bar 4 from the feed screw 6, two half-nuts 12 and 13 are mounted on'arms 14 and 15 made fast on the `traverse bar and so positioned that when the half-nut 12 engages the threaded portion 7 of the screw the halfnut 1.3 is out of engagement with the screw, but is adapted to be brought into engagement with the threaded portieri 8 thereof as soon as the halfnut l2 is thrown out ofl engagement with the threaded portion 7. As will be seen oninspection of Fig. 1, the traverse bar is moved to the left whenthe halt`-nut 12 is inv engagement with the threaded portion 7 of the screw, and when the halfnut 13 broghtintol engagement with the' threaded portion 8 of the screwfthe traverse bar is moved to the right. i i

In order to effect the reversal of movement of the traversebar at each end of its range ofmovement, mechanism is provided to throw one of the halfmuts out of engagement withthe corresponding threaded portion of the feedlscrew and to throw the other halfnut into engagement with the oppositely threaded portion of the Afeed-screw.' This ymechanism comprises anarm 16 rigidly secured to the traverse bar and the device illustrated in dean in rigs. 2 and 3. Thisdvi comprises a bed 17 having a groove 18 with undercut sides formed in its upper surface, a slide 19 arranged lforreciprocation in the groove 18, adjustable stops to limit the movement of the slide 19, and devices carried by the'slide to s hit the arm 16 at each end of the range of movement of the traverse bar so as to throw the active halfmut out of engagement with the feed-screw and throw the'other half-nut into engagement therewith.l Thestops by which the movement of the slide 19 is controlled'consist of a pair of nuts 2O and 21 mounted on al screw 22 supported on`the undersldeof the bed 17 in suitablebrackets 23. These nuts are engaged by a collar'24encircling the screw 22 supported on a bracket 25 which is secured to the slide 19 and works ina slot in.

the bed 17 Projecting upward from the slide v19 above the bracket 25 is a flat lug 26 which preferably has beveled edges, asshown in Fig. 2. Springs 27 andy 28 mounted on lugs rising from the ends of the slide 19 press normally against the edges of the lug 26 from opposite sides, as shown in Fig. 2. These springs 27 and in forming pockets to receive the arm 16 carried by the traverse bar.

When the arm 16 lies between the lug 2G and the spring 27 the half-nut 12 is in engagement with the threaded portion 7 oi the feed screw and movement to the leit is imparted to the traverse bar. `As the traverse bar moves to the left the collar 24 which is carried 28 are so arranged that they coperate with the lug 26 lug 26.

by the slide 19 movestoward the stop nut 20 and when the collar 24 engages the stop nut motion otheslide 19 is arrested. The movement of the traverse'bar to vthe left continues, however,Y as long as the half-nut 12 remains in engagement 4with the feed-screw and, as the traverse bar continues to move to the leftfthearrn 16 is forced forward against the spring 27', ,Whichis thereby forced out oi Contact with the lug As soon as the arm 16 passestlielug 26 the'pressure oi thefree end of the spring 27 against the arm throws the arm 16 over against the spring 28 and this movement of the armi?.V

rocks the traverse bar 4 suiiciently to "throiv-"thehalif nut 12 out of engagement withy the feed-screw' and lto bring theother half-nntl intoengagement with the threaded portion@ of the feed screw. The shifting' ,otA

the halfnuts 12 and 13 immediately reverses-the direction of movementoi the traverse bar and the arnr'l then lies in the pocket Abetween the spring 28 and the lug 2 6 and the movement of the traverse barto the right imparts movement to the slide 19 in the samey and brings the halsnut 12 again intoengagement with the threaded portion 7 of the feed-screw, and `throws the hali-nut 13 out of engagement, thus reversing the direction of movement of the traverse bar and starting it on its return movement toward the left.

From theiforegoing description and the accompanyo ing drawings it Will be seen that the range oi move- .ment of the traverse bar is determined bythefrange of4 movementaliowed the slide 19 on the bed A17 andr that the range oi movement of this slide is controlled by means of'stop nuts 20 and 21 on the screw,y 22. Consequentiy, 'in order toy vary the range of,movement or the traverse baz` it is only necessaryto alter the `position of one or both of the nuts 20 or 21-and it is unnecessary to change any element of the reversing mechanism. The adjustment oi the nuts 20 and21 can be made in-b senseo stantly without stopping skilled operative. o
